Features of Chrome Corundum Refractory Bricks

Stable Chemical Capacity

Chrome corundum bricks have great chemical resistance. They can resist acid and alkaline solutions. Besides, the chromic oxide can form a protection film that can avoid slag erosion.

High Refractoriness

Chrome and corundum both have high melting points. So the under load temperature of chrome corundum brick is up to 1700℃. In this situation, chrome corundum bricks can be used in many high-temperature industrial kilns.

Good Thermal Shock Resistance

In the production process, chrome and corundum can form a continuous solid solution. This structure can effectively improve the hardness of bricks. So the hardness of chrome corundum brick is better than corundum brick.

Oxidation Resistance

Chrome corundum refractory brick has good oxidation resistance. It will not oxide with other materials in the high-temperature equipment. In this situation, it belongs to environment-friendly material that can be reused.

Usages of Chrome Corundum Bricks

Compared with corundum brick, chrome corundum brick is used more widely.

Glass industry: glass kiln lining, brushed glass flow hole cover brick, and so on.
Steel industry: hot blast furnace lining, bottom, throat, ladles, and other equipment.
Nonferrous industry: melting furnaces, converters, anode furnaces, etc.
Petrochemical industry: thermal reactors, waste incinerators, etc.
